From young starlets and their straying boyfriends to longtime wives and their cheating husbands, love triangles are far too common in Hollywood. Which forbidden romance do YOU think is most scandalous?

No one is more prone to drama than actors, and there is perhaps no greater drama than the good old celebrity love triangle! Sandra Bullock, Ryan Reynolds and Scarlett Johansson are all rumored to be part of Hollywood’s latest triangle making headlines everywhere, and they aren’t the only recent additions either as Taylor Swift, Taylor Lautner and Jake Gyllenhaal also seem to be raising eyebrows with their on and off relationship!

First there was Tiger Woods, Elin Nordegren and sexy mistress Rachel Uchitel (not to mention his 15+ other alleged girls). Then, only weeks after winning the Oscar for Best Actress, Sandra was shocked to find out with the rest of the world her hubby of five years, Jesse James, was cheating on her with a tattooed stripper named Michelle “Bombshell” McGee.

Another major love triangle took the teen world by storm in Summer 2010. Demi Lovato and her best friend Joe Jonas started dating after months of build up, but the relationship quickly deteriorated and Joe quickly fell in love with Twilight actress Ashley Greene. Making matters that much worse, Demi, 18, checked into treatment in the fall, citing “emotional problems.” Yikes!
